Abstract
The study was carried out to investigate the prevalence of anemia concerning with both of iron and Vitamin A deficiency among primary school children, through estimation the adequacy of nutrients intakes as compared to the recommended Dietary Allowances (RDA) 1989 for school children in urban and rural, Assessment iron in hair and nails for primary school children, So, this work conducted to making biscuits formulas enriched with some nutrients from natural sources such as carrot, sweet potato and pumpkin powder, in addition to supplement sugar with black strap molasses, through investigate the chemical composition , determination of iron, vitamin A for raw materials, also the same measurements to all biscuits formulas that made from wheat flour (72% extraction) at different percentage with 10% for (carrot, pumpkin and sweet potato powder), Estimation the backing quality parameters and organolyptic properties for all biscuits formulas, determination the amino acids for selective biscuits formula, study chemical score of essential amino acids, biological value (BV) ,and protein efficiency ratio (PER). The results obtained from daily intake survey that there were decreased in iron intake compared with RDA in both urban and rural, also a decreased in vitamin A intake in rural sample. Also results revealed that biscuit made from wheat flour and (10%) carrot, pumpkin and sweet potato with other additives increase the amount of vitamin A compared with control sample. the replacement of sugar with black strap molasses caused increase in iron content of biscuit formula . Addition of pumpkin to sweet potato powder improved color in different biscuit mixtures. Selective biscuit formula gives a high overall acceptability and high ability value. Total E.A.A increased in selective biscuit (46.88, 50.70, 48.12, 46.58%) compared with control sample (44.90%). Methionine considered as a first restricted amino acid (R.A.A) and phenylalanine as the second one. When consumed 188.7, 192.3, 200.0 and 208.2gm from selective biscuits formula covered the daily requirement of iron and V.A for primary school children (9-12years). Biological value for selective biscuits formula arranged from 72.44 to 80.52.
